* Add StringRef::compare_numeric and use it to sort TableGen register records.Jakob Stoklund Olesen2010-05-261-0/+28
| | | | | | | This means that our Registers are now ordered R7, R8, R9, R10, R12, ... Not R1, R10, R11, R12, R2, R3, ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104745 91177308-0d34-0410-b5e6-96231b3b80d8
* Add an override to StringRef::getAsInteger which parses into an APInt.John McCall2010-02-281-12/+93
| | | | | | | | | | | | It gets its own implementation totally divorced from the (presumably performance-sensitive) routines which parse into a uint64_t. Add APInt::operator|=(uint64_t), which is situationally much better than using a full APInt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97381 91177308-0d34-0410-b5e6-96231b3b80d8
